I have a problem with the waveform display of the multitrack song. This consists of a click, backings and my drum track, which I would like to have displayed as a waveform for orientation. However, this waveform is overwritten after loading the click track, which makes no sense. After that, I can no longer generate a waveform for my drum track because the generate button is no longer visible on this track. Is there a solution to this?
